They also face firearms allegations after a Feb. 29, 2012, search of their residence on the 4200 block of Foothill Boulevard reportedly yielded two shotguns and a .22-caliber revolver.

The couple was not held to answer on a felony drug possession charge for what was purported to be 54.5 grams of psilocybin mushrooms discovered in a freezer at the house. However, deputy district attorney Brent Redelsperger acknowledged that no lab tests confirming the mushrooms' provenance was submitted for the hearing.

During Monday's hearing, Butte County probation officer Nathan Henry testified about the investigation that began when someone at Pioneer Shipping in Oroville reported receiving a package that contained marijuana.

Under questioning by Redelsperger, Henry said officers used shipping information to confirm the package came from the Korbys. Henry and other officers searched the residence on Feb. 29 and located 112 pounds of processed marijuana and 90 additional pounds of marijuana stalks or shake.

The marijuana was in jars, plastic bags and other containers. There were also two rooms that appeared to be used for growing and several plants in various, early stages of growth.

"There was boxes of marijuana throughout the entire residence," he said.

In addition to the marijuana and firearms, officers also located $17,400 in cash at various locations. Henry said the Korbys reportedly received money from real estate sales, but Thomas Korby was unemployed. Donna Korby reportedly told an officer she played poker professionally; the judge didn't allow that information because it was provided to a different officer after she invoked her Miranda right against self-incrimination.

Officers also found 11 medical marijuana doctor's recommendations, but none of them matched the name of the package's recipient. Henry said the processed marijuana found at the house exceeded the amount specified on the recommendations by 30 pounds.

A handwritten note was reportedly found in Donna Korby's bedroom saying there was a need to track what people in the circle were doing in providing marijuana to patients. The note mentioned offering the drug at an affordable price — between $100 to $400 per ounce, depending on quality.

During cross examination, Donna Korby's attorney, Michael Levinsohn of Los Angeles, questioned how the initial package was stopped. Henry said the store removed the marijuana from the package. The rest of the package was sent on its way after the store placed a notice in the package saying seized contraband would be turned over to officials.

Henry said he believed he took photos of the package and the shipping documents, but he didn't have them with him.

Levinsohn also questioned Henry's reliability as a witness because Henry initially said he wrote the search warrant on Feb. 23, 2012, but the record showed it had been authorized by a prosecutor and signed by a judge before that. Henry said it was a typo in his report.

On cross-examination by Thomas Korby's attorney, James Berglund, the officer said Thomas Korby expressed knowledge of the shipment, but apparently learned of it after the fact and after initially trying to discourage Donna Korby from shipping it.

During arguments, Levinsohn said the prosecution failed to prove who sent the package and the testimony was unreliable.

Regarding the other marijuana charges, he said it's not possible to determine whether there was too much marijuana on the site because no state law or guideline sets a limit. He argued that excess marijuana may be kept for long-term storage or if new members join the group.

Levinsohn said the different strains found are a sign it was being grown for medicinal purposes, and case law doesn't require collective or cooperative members to contribute to a grow beyond compensation for expenses.

Berglund argued that the prosecution didn't present evidence that applied to Thomas Korby.

Redelsperger responded that Donna Korby's name and cellphone number were on the package and Thomas Korby knew about the shipment.

Regarding the grow at the house, Redelsperger said the amount being grown exceeded the recommendations and was clearly for profitable sale, referring to the note. He said the law also doesn't allow for possession for potential new members.
